doubt about printf newbie
 
Hi, i hope you can help me to understand why the following program works even though i did not include the "#include<cstdio>"

#include<iostream>
int main()
{
printf("hello world");
}


Is it because iostream already includes printf??? or what's going on?

Re: doubt about printf newbie
 
iostream is a header file which is used for input/output in the C++ programming language. It is part of the C++ standard library. The name stands for Input/Output Stream.

In C++ and its predecessor, the C programming language, there is no special syntax for streaming data input or output. Instead, these are combined as a library of functions. Like the cstdio header inherited from C's stdio.h, iostream provides basic input and output services for C++ programs.

Hope this will help!!!!!
